Will going back to caveman ages solve most of problems?

Pros I can think of right away:

> no currency so that alone solve majority of bullchit
> Weaklings suffer (Many advantages like redditors ain't allowed free speech any part of world)
> Women learn their place again
> No more "elites" so world is more free place (because fat neckbeards mostly)

Cons :

> Can be fukd if other guy is stronger
Vegeta > Goku crew
Cathedral Chants only gym playlist crew
